CASING IN Two-PARTS FOR PACKING PARAGHUTES .Filed April 27, 1929 4 Sheets-Sheet 4 Patented Mar. 3, 1931 UNITED STATES PATENT OFFICE ROBERT HABERMEHL, DECEASED, BY THERESE HABERMEHL, NE GOEDERT, EXECU- TRIX, 0F BERLIN-SCHONEBERG, GERMANY CASING IN TWO PARTS FOR PACKING PARACHUTES Application filled April 27, 1929, Serial No. 358,743, and in Germany December 13, 1927.

The invention relates-to a casing in two parts for packing parachutes, of which one part is attached to the aeronaut and the other part to the ilying-machine.

While in the known divided packing-casings the outer part of the casing is connected with the flying-machine and retained by the latter during descent, the arrangement has, according to the present invention, been made so, that the outer part ofthe casing is attached to the aeronaut and surrounding the inner part of the casing connected with the flyingmachine. Hereby Iit is possible to attach the two part packing-casing, including' parachute, knapsack-like to the back of the aeronaut and to utilize the same as a seat-cushion. Further advantages will be disclosed lby the following description and claims.

Four embodiments of the invention are illustrated in the accompanying drawings by way of example, wherein:

Figure 1 illustrates a construction of the -parachute with divided packing-casing in longitudinal section,

Figure 2 is a plan-view of the packingcasing,

Figure 3 is a side-view. l

Figure 4 shows the unfolding of the parachute, after leaping olf of the aeronaut.

' Figure 13 shows the inner casing, receiving the parachute, in longitudinal section,

Figures 14' and 15 the modes of utilizing the parachute-bag as seatand back-cushion by the aeronaut and Figure 16 illustrates a somewhat modilied construction.

In Figures 1-6 the packing-casing, receiving the parachute 1, consists of an inner casing 2 and an outer casing 3, both consisting of machine.

tached to the aeronaut, by means of hooks 9` or other suitable fastening devices.

The cords 7 are shorter, than the supporting girth 8, in order to relieve the same from any tensile strains.

As the outer part of the casing 3 is attached to the aeronaut, the parachute-bag can be utilized by the aeronaut as backcushion, or as a seat-cushion, the outer part of the casing, being for this purpose provided at its upper part with eyes 14, or the like, in engagement with corresponding hooks arranged at suitable points on the aeronauts strap, that is about the height of the shoulder.

The open end of the outer part of the casing 3 is provided with eyes 10, through which a lock-wire 11, attached to the connectingcord 5 is passed in known manner (Figs. 1-3 and 6). The loose portionof the relatively long connecting-cord 5 can, as shown in Fig. 2, be inserted between the two parts of the casing 2, 3, while its end remains connected with the flying-machine.

During descent, the aeronaut first drops with the part of the parachute-bag attached to him, for several meters unobstructed, until he has passed beyond the range of the flying- The cord 5, connected with the dying-machine 6, is then tensioned, after having been pulled out of the parachute-bag, if the same had been pushed between the two parachute-casings 2, 3.

As soon as the cord lock-wire 1l connected thereto, is first removed from the eyes 10 of the outer part of the casing 3, so that both parts of the casing 2,- 3 are now only loosely telescoped. Dur- 5 is under tension, the

whereupon the parachute 1 in the inner casing is withdrawn together with the cords 4, and can unfold itself (Figs. 4, 5). The outer part of the casing 3 remains attached to the aeronaut, while the inner part of the casing remains attached to the flying-machine.

To facilitate the telescoping of the two parts of the casing 2, 3 the open end of the casing-part 3 can, as shown in Figs. 2,3 and 5, be indented or slotted on the edge.

To cover the lock-wire 11, when the parachute-bag is closed, covering-flaps 12, 13 can be provided. 'In the construction according to Figs. 1-4 of the drawings, several such covering-flaps 12 are provided on the inner casing-part 2, while according to Fig. 6 of the drawing, a common covering-flap 13 has been arranged on the outer casing 3. The flaps 12, 13 can be attached to one side yof the parachute-bag by sewing and placed loose over the locking-wire 11, but they may be detachably connected to the opposite sides of the casing, as for instance, by means of snaps or the`v like.

According to Figs. 7-15 the packing-casing for the parachute consists of an inner casing-part 2, receiving the parachute in folded condition and an outer casing-part 3 surrounding the latter and provided with foldable locking-flaps 15.

The inner casing-part 2 is connected with the flying-machine 6 (Fig. 12) by a drawcord 5, while the outer casing-part is attached to the aeronaut. The parachute-cords 4'are for this purpose connected with the retaining-ropes 8, passing through lower openings in the outer casing 3, ending in, hooks 9, by means of which the parachutebag is suspended in the eyes 16 of the aeronaut strap 17 (Figs. 14 and 15).

n order to hold the locking-flaps 15 of the outer casing 3 together, a pin or a cord- `loop 18 is preferably fastened on one lateral flap 15 (Fig. 11),'w`hich gan during overlapping of the other aps 15, be pushed into f metal eyes 19, pressed into the same. Into the'loop 18, inserted into the metal eyes 19, that is into the part projecting from the metal eyes 19, when the casing 3 is closed, a splint-like safety-element 20 can be inserted (Fig. 8), attached to the `draw-cord 5. For securing the splint 20, -a thin breakable cord 21 can be attached to a hole in the splint and connectedwith a ring 22, attached to one of the locking-fiaps 15 (Fig. l8).

If a pin with an openin for receiving the split 20, is used instead o the cord-loop 18, the said pin is preferably arranged to move, in order to be like the cord 18, flexible or adjustable in all directions. g

To cover ,the lock, one of the lockin -flaps 15 may be provided with a flap 23, w 'ch is placed over the locks 18, 19', 20, when the bag von which the retaining-ropes are fastened by means of a short cord-loop 26 or the like (Figs. 7-10). A supporting-strap can also be used and drawn through the casing, as

indicated in dotted lines at 81 in Fig. 11, to which the ropes are connected.

The parachute 1 isv during packing folded with its ropes 4 into the inner casing 2 (Fig. 13), whereupon the inner casing is inserted into the outer casing 3 and the locking-flaps 15 of the lattergfolded over one another and held together by the locks 18, 19, 2O (Fig. 8) The lock is then covered by the safety-liep 23, the end of which is pushed into the pocket 24 (Fig. 7). The draw-cord 5, which is about 6-15 In. long, to enable opening of the packing-casing and unfolding the parachute, only after the aeronaut has dropped beyond the range of the'flying-machine, can partly be placed betwseen the locking-liaps, that is between the inner and outer casin (Fig. 8).

The cord 5 connected with the flying-ma.- chine is, during the descent, first drawn from the packing-casing and the locking-flap 23 opened thereby (Fig. 8). As soon as the cord has completely been withdrawn and tensioned, the splint 20, connected with the cord 5', is by this tension drawn from the cordloop 18 or the drilled pin, and the lock of the outer casing 3 opened. In withdrawing the splint 20, the thin safety-cord 21 is torn, if one Mhas been used. The tensioned drawcord 5 pulls now at the inner casi'nl 2, and opens the upper locking-flap 15 (Fig. 9),

whereby said inner casing 1s pulled out of the outer casing 3 together with the parachute j (Fig. 10). The other locking-flaps 15 of the outer casing 3 opensimultaneously (Fig. 11) The parachute 1 is drawn from the casing 2 by the retaining-ropes 8 connected by cords 4 with the parachute-material contained in the casing'2, so that it can now unfold itself (Fig.` 12). The outer casin 3 is 'carried down, by the aeronaut suspen ed onthe unfolded parachute 1, while the inner casin 2 remains with the cord 5 and locking-splint 20, hanging on the :dying-machine (Fig. 12)

The parachute-bag can in its construction according to Figs. 4-7-15, be lfsed by the aeronaut as a seator Iback-cushion. The outer casing 3 is for this purpose also provided with rings 14, or the like (Fig. 14), which are placed into hooks 27, or the like, fastened in corresponding height, about the height of the shoulder, on the strap 17 of the aeronaut (Figs. 14115).

The locking-flaps 15 can be folded over one another, as shown in Fig. 16, in which case the superfluous length ofdraw-cord is, during carrying of the parachute-bag, pushed ,casing and its other end adapted to bev fastened to parts of an aircraft, an outer covering provided with overlapping flaps and adapted to surround the inner casing with the parachute therein and to be attached to the aeronaut, and means for normally holding said flaps in overlapping relation and carried by said connecting line.-
